Widget description

An index widget gives you an index for fast access to whichever group of other UI items one might have.

It’s a list of text items (usually letters, for alphabetically ordered access).

Index widgets are by default hidden and just appear when the user clicks over it’s reserved area in the canvas. In its default theme, it’s an area one finger wide on the right side of the index widget’s container.

When items on the index are selected, smart callbacks get called, so that its user can make other container objects to show a given area or child object depending on the index item selected. You’d probably be using an index together with List, Genlist or Gengrid.

Emitted signals

  • changed - When the selected index item changes. event_info is the selected item’s data.

  • delay,changed - When the selected index item changes, but after a small idling period. event_info is the selected item’s data.

  • selected - When the user releases a mouse button and selects an item. event_info is the selected item’s data.

  • level,up - when the user moves a finger from the first level to the second level

  • level,down - when the user moves a finger from the second level to the first level

The delay,changed event has a delay on change before the event is actually reported and moreover just the last event happening on those time frames will actually be reported.
